Design of zwitterionically modified alginates and their in vitro characterizations. a Schematic illustration of zwitterionically modified alginate microcapsules encapsulating islets. b Synthetic pathway and 1H NMR characterization of sulfobetaine (SB)-modification of alginate. c Adsorption of FITC-labeled fibrinogen and lysozyme on the surfaces of different alginate hydrogels quantified by ImageJ. Mean ± SEM; n = 6; *P < 0.05. d Quantification of TNF-α secretion from macrophages cultured on different surfaces. Mean ± SEM; n = 5; *P < 0.05. e Chemical structures of CB1-alginate and CB2-alginate conjugates
